To all whomit may concern:

Be it known that I, JEAN WEBB, Jr.,

residing at New York, in the countyof New York and State of New York, have invented certain new and useful Improvements in Plow-Shoes, of which the following is a] specification.

My invention relates to certain new and tion filed by J. F. Webb, Sr.,and-myself on i October'12, 1914, Serial NO. 866,356, and the application filed by myself on April 27, 1914, Serial No. 834,867, and thepresentinvention has particular relation'tothe path clearing device or contact shoewhich vi'sdesigned to effect the cofiperativeconnectio'n between the track ramp and the train carried apparatus.

Practical tests and experimentationha've .1

proven that adequate provision must be made for the removal of snow and ice from the ramp device in order to insure full electrical contact throughout the length of the ramp. In order that this may be ac'com plished with the greatest completeness and efliciency, I have provided a contact shoe or plow which forms the subject matter of the present invention, and the essential characteristic of which is the provision of a set of grooves or flutes on the underside of the plow shoe proper, so designed as to form auxiliary cutting edges to assist in the com.- plete removal of snow and ice from the ramp and discharge the same to one side.

More specifically, the invention comprises a shoe which is composed of a contact plate or shoe proper, the front'edge, at least, of which is beveled to present a sharp plow member tothe ramp to shave off the snow and ice, as it were, the under side or contacting face of the shoe proper being grooved to leave a rib or ribs that preferably extend parallel to the front cutting edge of the shoe and have sharpened edges to complete the removal of snow and ice that might remain on the track after the front cutting edge has passed, the shoe being supported by a neck that joins it with a head, by means of which the shoe is connected with the plunger of the train carried apparatus.

In its more subordinate nature, the invention embodies those novel details of construction, combination and arrangement of parts, all of. which .will be first fully de- Specification of Letters. Batent. Application filed May15,19 15. Serial M28436. 1

- scribed, then be specifically pointed out in the appended claims, andillustrated in the accompanying drawings, in which: t

Figure 1 is a perspective view of the preferred; form of the invention. Fig. 2 is a top plan view of'the same, Fig.3 isfan in verted plan @view showing the location of the grooves and ribs. Fig. 4 is a central vertical longitudinal section and part elevation illustrating the manner ofapplying the shoe to the plunger of the train carried apparatus. F1g.,5 is an lnverted plan view of amodified form of the shoe. Fig, 61is an.

inverted plan view of a further 'modification.

,In the drawing,=like numerals of refer-x ence designate like parts in all ofrthe figures, and by reference to the same, it will be observed thatl designates the support of the train stopping apparatus in which: the plunger 2 is vertically reoiprocable, being held down by a spring that engages the plate 6 which rests on the heads of the bolts 5; The plunger Qhas a bore 4 in communi cation with the train pipe of the airbrake 1 system and a counterbore 3 to receive the nipple 12 of the head 10 of the shoe, the

head 10 being secured to the plunger 2 by the bolts 5.

7 designates the shoe proper which is in the nature of a flat plate, the side faces 14 of which are preferably parallel to the direction of traflic, while the front and back edges arebeveled at 13 and extend diagonally across the line of travel to present a shearing edge to the ramp 18 (see dotted lines Fig. 4) and shear off any coating of snow, ice, orother material that may impair a good mechanical and electrical contact between the ramp and the shoe. The shoe proper 7 is supported by a neck 8, having strengthening ribs 9, from the head 10, it being understood that the shoe 7, neck 8, ribs 9 and head 10 are preferably integrally formed. The object of making the head 8 of a weakened construction is, in case of the encountering of a non-yielding obstruction along the roadway, that the neck 8 will break to release the air from the bore 4 of the plunger 2 via the bore 17 of the shoe and thereby set the brakes.

11. designates the holes, through whic the bolts'5 pass, in the head 10.

It will be observed that the under face of the shoe proper 7 is provided with one or more grooves 15 to provide sharp edges 16 to assist in cutting the snow and ice from the ramp 18 in the event that the front cutting edge of the shoe fails to remove all of the material from the ramp. The grooves 15 are preferably made to extend parallel to the front cutting edge and in the preferred construction of shoe the shoe is made reversible, that is to say, the front and back faces 13 are both beveled and either may be used as a front edge. Furthermore, this type of shoe is especially adapted for the purpose, because it will serve to clear the ramp whether the engine be running for wardly or backwardly. Instead of making the shoe proper 7 of a general diamond shape in plan view, as indicated in Figs. 2 and 3, it may be shaped as indicated in Fig. 5, or as indicated in Fig. 6, the grooves 15 being provided and extending parallel to the front edges 13 of the shoe.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art.

What I claim is 1. A plow shoe comprising a shoe plate, the front face ofwhich is beveled to present a sharp cutting edge, the under face of said .shoe plate being grooved to present auxilsaid shoe plate having a beveled front edge extending crosswise, the under face of said shoe plate being grooved parallel to said front cutting edge.

4. In a plow, a shoe proper comprising a shoe plate, the front edge of which. is beveled and extending at an angle to the line of traffic, the under side of said shoe plate being grooved to provide auxiliary cutting edges, and a support extending upwardly from said shoe plate.

5. In a path clearing device, a plow shoe comprising a head, a shoe plate and a connecting neck between the same, said shoe plate having its front and back edges beveled to present shearing edges, the under face of said shoe plate being flat and grooved parallel to said shearing edges to present auxiliary cutting edges, substantially as shown and for the purposes described.
